QUESTION
I am not a professional programmer but I want to create an small Julia machine learning package which is called neural spline flows. These networks are invertible neural networks which are mostly used to estimate an integral using the Monte Carlo method. I want to use this package as my scientific resume. The models are basically created using Flux or Knet. But the problem is that I am not satisfied with what I do. My codes are ugly and don't look like the ones written by professional programmers. Should I focus on learning some advanced aspects of Julia before creating my package? I don't want to waste my time.

Answered 2020-May-10 at 10:14Julia ships with its own package manager call Pkg
. The documentation takes you through the steps from starting a package from scratch all the way through adding tests and registering it with the general registry (which will allow other users to just pkg> add YourPackage
from the Julia package manager).
You can find it here: https://julialang.github.io/Pkg.jl/v1/creating-packages/
There are also user packages that help with creating packages, examples include
- PkgSkeleton.jl - as the name suggests, a very "bare bones" approach to get up and running quickly
- PkgTemplates.jl - more fully featured, but as the Readme says currently in a state of restructuring.
Generally the bar for creating packages in Julia for new users is pretty low I would say (although my experience in other languages is limited!), which is probably one of the great strengths of the ecosystem.
And to address your worries about the "look" of your code: I wouldn't worry about it too much, if you want to share your code for others to use what matters in the first instance is the API and whether it is user friendly. The difference between your code and what you perceive to be "professional" code should only matter to the extent that your code is less performant because of a suboptimal coding style - but I don't think that should keep you from publishing a package, if others find it useful and notice obvious performance issues they might even help you fix them and thereby improve your package, which is the whole idea of open source!
QUESTION
I have started using Julia.I read that it is faster than C. So far I have seen some libraries like KNET and Flux, but both are for Deep Learning. also there is a command "Pycall" tu use Python inside Julia.
But I am interested in Machine Learning too. So I would like to use SVM, Random Forest, KNN, XGBoost, etc but in Julia.
Is there a native library written in Julia for Machine Learning?
Thank you
...ANSWER
Answered 2019-Oct-10 at 15:48A lot of algorithms are just plain available using dedicated packages. Like BayesNets.jl
For "classical machine learning" MLJ.jl which is a pure Julia Machine Learning framework, it's written by the Alan Turing Institute with very active development.
For Neural Networks Flux.jl is the way to go in Julia. Also very active, GPU-ready and allow all the exotics combinations that exist in the Julia ecosystem like DiffEqFlux.jl a package that combines Flux.jl and DifferentialEquations.jl.
Just wait for Zygote.jl a source-to-source automatic differentiation package that will be some sort of backend for Flux.jl
Of course, if you're more confident with Python ML tools you still have TensorFlow.jl and ScikitLearn.jl, but OP asked for pure Julia packages and those are just Julia wrappers of Python packages.
QUESTION
I use Tensorflow for deep learning work, but I was interested in some of the features of Julia for ML. Now in Tensorflow, there is a clear standard that protocol buffers--meaning TFRecords format is the best way to load sizable datasets to the GPUs for model training. I have been reading the Flux, KNET, documentation as well as other forum posts looking to see if there is any particular recommendation on the most efficient data format. But I have not found one.
My question is, is there a recommended data format for the Julia ML libraries to facilitate training? In other words, are there any clear dataset formats that I should avoid because of bad performance?
Now, I know that there is a Protobuf.jl
library so users can still use protocol buffers. I was planning to use protocol buffers for now, since I can then use the same data format for Tensorflow and Julia. However, I also found this interesting Reddit post about how the user is not using protocol buffers and just using straight Julia Vectors.
https://www.reddit.com/r/MachineLearning/comments/994dl7/d_hows_julia_language_mit_for_ml/
I get that the Julia ML libraries are likely data storage format agnostic. Meaning that no matter what format in which the data is stored, the data gets decoded to some sort of vector or matrix format anyway. So in that case I can use whatever format. But just wanted to make sure I did not miss anything in the documentation or such about problems or low performance due to using the wrong data storage format.

Answered 2019-Jul-18 at 01:55For in-memory use just use arrays and vectors. They're just big contiguous lumps of memory with some metadata. You can't really get any better than that.
For serializing to another Julia process, Julia will handle that for you and use the stdlib Serialization module.
For serializing to disk you should either Just use Serialization.serialize (possibly compressed) or, if you think you might need to read from another program or if you think you'll change Julia version before you're done with the data you can use BSON.jl or Feather.jl.
In the near future, JLSO.jl will be a good option for replacing Serialization.

QUESTION
I am trying to create a network in tensor flow with multiple softmax outputs, each of a different size. The network architecture is: Input -> LSTM -> Dropout. Then I have 2 softmax layers: Softmax of 10 outputs and Softmax of 20 Outputs. The reason for this is because I want to generate two sets of outputs (10 and 20), and then combine them to produce a final output. I'm not sure how to do this in Tensorflow.
Previously, to make a network like described, but with one softmax, I think I can do something like this.
...ANSWER
Answered 2017-Oct-13 at 07:48You can do the following on the output of dynamic_rnn
that you called output[0]
in order to compute the two softmax and the corresponding losses:
